test sweep: cover utils/ + core/mouse/ (T-91)

Adds two test files closing the last two pure-Dart sub-areas in
`lib/src/terminal/src/`:

`test/terminal/utils/utils_test.dart` — 51 tests covering:
- Ascii.isNonPrintable (control chars + DEL).
- hashValues (every optional arg slot, 2..20 inclusive) +
  hashList (including the documented zero-on-empty short-circuit).
- ByteConsumer (single-block + cross-block consume, peek's
  consume-rollback path, rollback within block + across consumed
  blocks, rollbackTo, unrefConsumedBlocks, reset).
- IndexAwareCircularBuffer (push/trim, pushAll, pop, [] / []=,
  clear, forEach, remove with count clamp / no-op, insert in the
  middle / at end / at full ring, insertAll, trimStart, replaceWith
  with truncate-from-head, swap, maxLength setter incl. error +
  no-op cases, debugDump, IndexedItem mixin attach/detach/index).
- UnicodeV11.wcwidth (control chars, printable ASCII, DEL+C1,
  combining marks BMP+high-plane, wide chars BMP+high-plane,
  unmapped high-plane default, version field).
- The push wrap branch where _startIndex resets to 0 after a full
  revolution (last circular_buffer line).

`test/terminal/mouse/mouse_test.dart` — 21 tests covering:
- TerminalMouseButton ids + isWheel for the 7 enum values.
- MouseReporter for all four MouseReportMode shapes (normal with
  >223 null-byte clamp, utf with the 2015-limit clamp, sgr's M/m
  pair, urxvt's button+32 / 3-on-up encoding).
- TerminalMouseEvent constructor.
- CascadeMouseHandler first-non-null semantics.
- ClickMouseHandler — only fires on clickOnly + down + button id
  < 3; null otherwise. UpDownMouseHandler — fires on every
  upDownScroll* mode; drops wheel-up; passes wheel-down. Default
  defaultMouseHandler routes through both.

Coverage delta:
- utils/ascii.dart: 0/2 → 2/2.
- utils/byte_consumer.dart: 28/42 → 42/42.
- utils/circular_buffer.dart: 71/130 → 130/130.
- utils/hash_values.dart: 16/36 → 36/36.
- utils/unicode_v11.dart: 16/27 → 27/27.
- core/mouse/handler.dart: 3/34 → 34/34.
- core/mouse/reporter.dart: 0/17 → 17/17.
- (utils/char_code.dart, utils/lookup_table.dart already at 100%
  from earlier reflow + parser work; mouse/button.dart,
  mouse/button_state.dart, mouse/mode.dart are pure enums with no
  executable lines.)
- Total project: 54.62% → 56.40%; coverage_floor bumped 54 → 56.

Two pre-existing `// ignore_for_file: constant_identifier_names`
suppressions that lacked documented reasons get inline
justifications:
- `lib/src/terminal/src/utils/ascii.dart` — RFC 20 / ISO 646
  control-character names; lowerCamelCase would diverge from every
  spec/man-page reference.
- `lib/src/terminal/src/utils/unicode_v11.dart` — Unicode 11
  wcwidth tables vendored as-is; future re-vendoring stays a
  verbatim paste.

Both fall under the same "FFI / spec-shaped names" pattern as the
libc.dart suppression (D-66 era).

"title": "reflow tail-anchor reparenting can dangle on partially-filled lines",
"description": "**File:** `lib/src/terminal/src/core/reflow.dart` (`_LineReflow._addPart`).\n\n**Bug:** Anchors whose x-coordinate sits past the source line's `trimmedLength` get reparented onto whatever `_builder._result` is active at that moment. After the main reparenting loop has run with `lineFilled` on the final iteration, `_builder.take()` has already moved the filled line into `_lines` and reset `_result` to a fresh empty `BufferLine`. The post-loop block (lines 144-150 in the current source) then reparents the tail anchor onto that fresh empty line. If no further content lands in the builder before `finish()` exits — which is the case whenever the post-loop block fires on a non-wrapped logical line — the empty builder line is never appended to `_lines`, and the anchor ends up pointing to a `BufferLine` that the reflow result never includes.\n\n**Trigger paths in production code:**\n\n1. `SelectAllTextIntent` (`lib/src/terminal/src/ui/shortcut/actions.dart:60-63`) creates the end anchor at `x = terminal.viewWidth`. That is *exactly* the past-trimmedLength position for every partially-filled line in the buffer. Any user who Ctrl+A's and then resizes the terminal narrower hits the bug for every short line in the scrollback.\n2. `selectCharacters` / mouse drag selection (`lib/src/terminal/src/ui/render.dart:286-298`) — anchors are clamped to `[0, viewWidth-1]` but can sit past `trimmedLength` on a partially-filled line. Drag past content end + resize narrower trips the bug.\n3. `selectWord` (`render.dart:264-275`) — `getWordBoundary` walks until a separator OR `viewWidth`, so the end anchor of a near-edge word can land at `x = viewWidth` and trip the bug on resize.\n\n**Symptom:** selection extents lose track of content after a width change. Visible highlight stops moving with the underlying selection, or extents disappear off the rendered buffer entirely. No exception is thrown — the dangling anchor still has a valid `BufferLine` reference, it just isn't on a line in the visible buffer.\n\n**Acceptance:**\n- New unit test in `test/terminal/core/core_test.dart` (or a sibling) that:\n - Constructs a partially-filled source line and an anchor past `trimmedLength`,\n - Runs reflow shrink,\n - Asserts the anchor's owning line is *in the reflow output list*, not dangling.\n- The existing widget-level select-all behaviour still works on resize: a Ctrl+A across the buffer followed by a narrower resize keeps the selection's end anchor pointing to a line in the reflowed result.\n- No regression in the existing reflow tests (the tail-clamp cases, wide-char boundaries, multi-line wrapped runs).\n\n**Investigation notes (do not skip):**\n\nThe fix is conceptually small — the reparented tail anchor must land on a line that gets emitted. Two candidate shapes:\n\n- **Skip the reparent entirely.** Anchors past `trimmedLength` arguably shouldn't survive a shrink that drops their column. Risk: callers expect every anchor on the source to be reparented somewhere; silently disposing them changes semantics.\n- **Force `finish()` to flush the builder line.** Whenever the tail-anchor branch fired during `_addPart`, set a flag, and have `finish()` emit the builder line even if `isEmpty`. Risk: empty trailing lines start showing up in the reflow result, which would break callers that assume reflow returns only content lines (resize loop in `Buffer.resize` pads to viewport height after, so an extra empty might be benign there but worth checking).\n\nDon't pick one without re-reading the full reflow flow + every caller of `reflow()`. The selection round-trip is also tested at the widget layer indirectly — verify `make test-a11y` still passes after the change.\n\n**Surfaced from:** T-91 test sweep (commit 3196c49). The 100% coverage on reflow.dart was achieved by exercising this branch but explicitly *not* asserting on the resulting line being in the output — see the test comment.\n\n**Cross-references:** T-91 (epic parent for the test sweep that found this), T-89 (coverage epic), the test in `test/terminal/core/core_test.dart` group `reflow` named \"anchors on the source line tail (past trimmedLength) get reparented\" documents the current (buggy) behaviour.\n",
